Do we still use Black Hawks

Former Marine Infantry Rifleman explains why (except the VH-60 White Hawks flown by HMX-1) the USMC doesnt use the Black Hawk Multirole Helicopter

One of the few military branches that does not use the iconic Black Hawk helicopter is the US Marine Corps. Why?

During the last 40 years, the remarkable Black Hawk multirole helicopter has fought its way in and out of countless combat zones to deliver and extract troops, save lives as a MEDEVAC or casualty evacuation platform, provide critical supplies to troops, deliver emergency supplies during natural disasters, and perform as an aerial firefighter and border patroller.

The Black Hawk serves with the US military and the armed forces of 28 other countries worldwide as a tough, reliable utility helicopter.

More than 4,000 Black Hawks of all types are in service worldwide today. The US Army is the largest operator with 2,135 H-60 designated aircraft. The same aircraft sold internationally direct from Sikorsky acquires the S-70 designation.

One of the few military branches that does not use the iconic Black Hawk is the US Marine Corps. Why?

Marines dont fly Black Hawks for a couple of reasons, Jonathan Burba, former infantry rifleman at US Marine Corps, explains on Quora. First, Marine Corps aircraft have to be able to operate off of a ship. The MV-22 Osprey and the CH-53E Super Stallion [and in the future the CH-53K King Stallion] are both huge, but are capable of adjusting to fit on a flight deck. Both aircraft are large, but they actually fold for easy storage.

The Ospreys and Super Stallions also have a lot more cargo capacity than a Blackhawk. The Black Hawk can carry 11 loaded troops, the Osprey carries twice that, the Super Stallion can carry 50 or 60 depending on how the interior is arranged. As far as weight goes, the Blackhawk can carry up to 9000 lbs, the Osprey and Super Stallion carry 15,000 lbs and 36,000 lbs respectively. Since we operate from the sea, its helpful to be able to sling vehicles such as Hummers, JLTVs and LAVs onto shore by helicopter, and since were operating off of a very small airport, all of the birds have to be able to handle a lot of different jobs. We didnt use Hueys all that often the units Ive served with, Ive flown on 2 I think. I cant tell you how may CH-53s Ive been on, it was usually that or the CH-46, the Ospreys were still being developed when I got out so I didnt get to fly on those personally.

Burba concludes;

The closest the Marine Corps has to the Black Hawk are the helicopters used by HMX-1 to fly the president. The Marine One birds are from the Black Hawk family, but all the VH-60 White Hawks are being retired and replaced with a new helicopter based on the Sikorsky S-92 in the near future though.

Lockheed F-117 Nighthawk

American stealth ground-attack aircraft

The Lockheed F-117 Nighthawk is a retired American single-seat, subsonic twin-engine stealth attack aircraft developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). It was the first operational aircraft to be designed with stealth technology.

Work on what would become the F-117 was commenced in the 1970s as a means of countering increasingly sophisticated Soviet surface-to-air missiles (SAMs). During 1976, the Defense Advanced Research Projects Agency (DARPA) issued Lockheed with a contract to produce the Have Blue technology demonstrator, the test data from which validated the concept. On 1 November 1978, it was decided to proceed with the F-117 development program. A total of five prototypes would be produced; the first of which performed its maiden flight during 1981 at Groom Lake, Nevada. The first production F-117 was delivered in 1982, and its initial operating capability was achieved in October 1983. All aircraft were initially based at Tonopah Test Range Airport, Nevada.

The aircraft's faceted shape (made from two-dimensional flat surfaces) heavily contributes to its relatively low radar cross-section of about 0.001m² (0.0108sqft). To minimize its infrared signature, it has a non-circular tail pipe that mixes hot exhaust with cool ambient air and lacks afterburners; it is also restricted to subsonic speeds as breaking the sound barrier would produce an obvious sonic boom that would increase both its acoustic and infrared footprints. While its performance in air combat maneuvering was less than that of most contemporary fighters, it was strictly an attack aircraft despite being commonly referred to as the "Stealth Fighter". For this reason, it is equipped with integrated sophisticated digital navigation and attack systems, targeting being achieved via a thermal imaging infrared system and a laser rangefinder/laser designator. It is aerodynamically unstable in all three aircraft principal axes and thus requires constant flight corrections via a fly-by-wire (FBW) flight system to maintain controlled flight.

Even years following its entry to service, the F-117 was a black project, its existence being denied by USAF officials. On 10 November 1988, the F-117 was publicly acknowledged for the first time. Its first combat mission was flown during the United States invasion of Panama in 1989. The last of 59 production F-117s were delivered on 3 July 1990. The F-117 was widely publicized for its role in the Gulf War of 1991, having flown approximately 1,300 sorties and scored direct hits on what the US called 1,600 high-value targets in Iraq. F-117s also participated in the conflict in Yugoslavia, during which one was shot down by a surface-to-air missile (SAM) in 1999. It was also active during Operation Enduring Freedom in 2001 and Operation Iraqi Freedom in 2003. The USAF retired the F-117 in April 2008, primarily due to the fielding of the F-22 Raptor.^[3] Despite the type's official retirement, a portion of the fleet has been kept in airworthy condition, and F-117s have been observed flying since 2009.^[4]

Development[edit]

Background and Have Blue[edit]

In 1936, Robert Watson Watt, a British engineer who invented radar, noted that measures to reduce an object's radar cross-section (RCS) could be used to evade radar detection.^[5] In 1964, Pyotr Ufimtsev, a Soviet mathematician, published a seminal paper titled Method of Edge Waves in the Physical Theory of Diffraction in the journal of the Moscow Institute for Radio Engineering, in which he showed that the strength of the radar return from an object is related to its edge configuration, not its size.^[6] Ufimtsev was extending theoretical work published by the German physicist Arnold Sommerfeld.^[7][8][9] Ufimtsev demonstrated that he could calculate the RCS across a wing's surface and along its edge. The obvious and logical conclusion was that even a large aircraft could reduce its radar signature by exploiting this principle. However, the resulting design would make the aircraft aerodynamically unstable, and the state of computer technology in the early 1960s could not provide the kinds of flight computers which would later allow aircraft such as the F-117 and B-2 Spirit to stay airborne. By the 1970s, when Lockheed analyst Denys Overholser found Ufimtsev's paper, computers and software had advanced significantly, and the stage was set for the development of a stealth airplane.^[10][11]

The F-117 was born after the Vietnam War, where increasingly sophisticated Soviet surface-to-air missiles (SAMs) had downed heavy bombers.^[12] The heavy losses inflicted by Soviet-made SAMs upon the Israeli Air Force in the 1973 Yom Kippur war also contributed to a 1974 Defense Science Board assessment that in case of a conflict in Central Europe, air defenses would likely prevent NATO air strikes on targets in Eastern Europe.^[13]

It was a black project, an ultra-secret program for much of its life; very few people in the Pentagon knew the program even existed.^[14][15][11] The project began in 1975 with a model called the "Hopeless Diamond"^[16][17][18] (a wordplay on the Hope Diamond because of its appearance). The following year, the Defense Advanced Research Projects Agency (DARPA) issued Lockheed Skunk Works a contract to build and test two Stealth Strike Fighters, under the code name "Have Blue".^[19][20] These subscale aircraft incorporated jet engines of the Northrop T-38A, fly-by-wire systems of the F-16, landing gear of the A-10, and environmental systems of the C-130.^[19] By bringing together existing technology and components, Lockheed built two demonstrators under budget, at $35million for both aircraft, and in record time.^[19] Undersecretary of Defense for Research and Engineering William J. Perry was instrumental in shepherding the project.^[21]

The maiden flight of the demonstrators occurred on 1December 1977.^[22][23] Although both aircraft crashed during the demonstration program, test data gathered proved positive.^[24][25] The success of Have Blue led the government to increase funding for stealth technology. Much of that increase was allocated towards the production of an operational stealth aircraft, the Lockheed F-117, under the program code name "Senior Trend".^[26][27]

Senior Trend[edit]

The decision to produce the F-117 was made on 1 November 1978, and a contract was awarded to Lockheed Advanced Development Projects, popularly known as the Skunk Works, in Burbank, California.^[28][29] The program was led by Ben Rich, with Alan Brown as manager of the project.^[30][31] Rich called on Bill Schroeder, a Lockheed mathematician, and Overholser, a mathematician and Radar Specialist, to exploit Ufimtsev's work. The three designed a computer program called "Echo", which made it possible to design an airplane with flat panels, called facets, which were arranged so as to scatter over 99% of a radar's signal energy "painting" the aircraft.^[10][32][30]

The first YF-117A, serial number 79-10780, made its maiden flight from Groom Lake ("Area 51"), Nevada, on 18 June 1981,^[33][34] only 31 months after the full-scale development decision. The first production F-117A was delivered in 1982, and operational capability was achieved in October 1983.^[7][35] The 4450th Tactical Group stationed at Nellis Air Force Base, Nevada, were tasked with the operational development of the early F-117, and between 1981 (prior to the arrival of the first models) and 1989 they used LTV A-7 Corsair IIs for training, to bring all pilots to a common flight training baseline and later as chase planes for F-117A tests.^[36]

The F-117 was secret for much of the 1980s. Many news articles discussed what they called an "F-19" stealth fighter, and the Testor Corporation produced a very inaccurate scale model. When an F-117 crashed in Sequoia National Forest in July 1986, killing the pilot and starting a fire, the USAF established restricted airspace. Armed guards prohibited entry, including firefighters, and a helicopter gunship circled the site. All F-117 debris was replaced with remains of a F-101A Voodoo crash stored at Area 51. When another fatal crash in October 1987 occurred inside Nellis, the military again provided little information to the press.^[37]

The USAF denied the existence of the aircraft until 10 November 1988, when Assistant Secretary of Defense J. Daniel Howard displayed a grainy photograph at a Pentagon press conference, disproving the many inaccurate rumors about the shape of the "F-19".^[38] After the announcement, pilots could fly the F-117 during daytime and no longer needed to be associated with the A-7, flying the T-38 supersonic trainer for travel and training instead.^[39] In April 1990, two F-117s flew to Nellis, arriving during daylight and publicly displayed to a crowd of tens of thousands.^[40][41]

Five Full Scale Development (FSD) aircraft were built, designated "YF-117A".^[42] The last of 59 production F-117s were delivered on 3 July 1990.^[35][43] As the USAF has stated, "Streamlined management by Aeronautical Systems Center, Wright-Patterson AFB, Ohio, combined breakthrough stealth technology with concurrent development and production to rapidly field the aircraft... The F-117A program demonstrates that a stealth aircraft can be designed for reliability and maintainability."^[2]

Designation[edit]

The operational aircraft was officially designated "F-117A".^[44][5] Most modern U.S. military aircraft use post-1962 designations in which the designation "F" is usually an air-to-air fighter, "B" is usually a bomber, "A" is usually a ground-attack aircraft, etc. (Examples include the F-15, the B-2 and the A-6.) The F-117 is primarily an attack aircraft,^[1] so its "F" designation is inconsistent with the Department of Defense system. This is an inconsistency that has been repeatedly employed by the USAF with several of its attack aircraft since the late 1950s, including the Republic F-105 Thunderchief and General Dynamics F-111 Aardvark. A televised documentary quoted project manager Alan Brown as saying that Robert J. Dixon, a four-star USAF general who was the head of Tactical Air Command, felt that the top-notch USAF fighter pilots required to fly the new aircraft were more easily attracted to an aircraft with an "F" designation for fighter, as opposed to a bomber ("B") or attack ("A") designation.^[45][46]

The designation "F-117" seems to indicate that it was given an official designation prior to the 1962 U.S. Tri-Service Aircraft Designation System and could be considered numerically to be a part of the earlier "Century series" of fighters. The assumption prior to the revealing of the aircraft to the public was that it would likely receive the F-19 designation as that number had not been used. However, there were no other aircraft to receive a "100" series number following the F-111. Soviet fighters obtained by the U.S. via various means under the Constant Peg program^[47] were given F-series numbers for their evaluation by U.S. pilots, and with the advent of the Teen Series fighters, most often Century Series designations.^[48]

As with other exotic military aircraft types flying in the southern Nevada area, such as captured fighters, an arbitrary radio call of "117" was assigned. This same radio call had been used by the enigmatic 4477th Test and Evaluation Squadron, also known as the "Red Hats" or "Red Eagles", that often had flown expatriated MiG jet fighters in the area, but there was no relationship to the call and the formal F-19 designation then being considered by the USAF. Apparently, use of the "117" radio call became commonplace and when Lockheed released its first flight manual (i.e., the USAF "dash one" manual for the aircraft), F-117A was the designation printed on the cover.^[49]

When the USAF first approached Lockheed with the stealth concept, Skunk Works Director Kelly Johnson proposed a rounded design. He believed smoothly blended shapes offered the best combination of speed and stealth. However, his assistant, Ben Rich, showed that faceted-angle surfaces would provide a significant reduction in radar signature, and the necessary aerodynamic control could be provided with computer units. A May 1975 Skunk Works report, "Progress Report No. 2, High Stealth Conceptual Studies", showed the rounded concept that was rejected in favor of the flat-sided approach.^[50][51][52] The resulting unusual design surprised and puzzled experienced pilots; a Royal Air Force (RAF) pilot who flew it as an exchange officer stated that when he first saw a photograph of the still-secret F-117, he "promptly giggled and thought [to himself] 'this clearly can't fly'".^[53]

The single-seat F-117 is powered by two non-afterburning General Electric F404 turbofan engines. They were extensively modified to suit a stealthy aircraft, such as to have a cooler operational temperature, and somewhat resembled a turbojet instead.^[54] The engine was redesigned to produce a minimum of mass thrust, which eased the task of designing a suitable inlet and nozzle. To obscure the engine from enemy radar, a conductive metal mesh grill was installed upon in the intake while the exhaust gases were intentionally mixed with cool air to lower the thermal signature as well.^[55]

The aircraft is air refuelable and features a V-tail. The maximum speed is 623mph (1,003km/h; 541kn) at high altitude, the max rate of climb is 2,820 feet (860m) per minute, and service ceiling is 43,000 to 45,000 feet (13,000 to 14,000m).^[56][57] The cockpit was quite spacious, with ergonomic displays and controls, but the field of view was somewhat obstructed with a large blind spot to the rear.^[58] The aircraft itself is approximately the size of an F-15 Eagle.

Avionics[edit]

Early stealth aircraft were designed with a focus on minimal radar cross-section (RCS) rather than aerodynamic performance, as such, the F-117 is aerodynamically unstable in all three aircraft principal axes and require constant flight corrections from a fly-by-wire (FBW) flight system to maintain controlled flight.^[59][60] It is equipped with quadruple-redundant fly-by-wire flight controls. To lower development costs, the avionics, fly-by-wire systems, and other systems and parts were derived from the General Dynamics F-16 Fighting Falcon, Boeing B-52 Stratofortress, McDonnell Douglas F/A-18 Hornet, and McDonnell Douglas F-15E Strike Eagle.^[61] To maintain a high level of secrecy, components were often rerouted from other aircraft programs, ordered using falsified addresses and other details, while $3 million worth of equipment was removed from USAF storage without disclosing its purpose.^[62]

The aircraft is equipped with sophisticated navigation and attack systems integrated into a digital avionics suite. It navigates primarily by GPS and high-accuracy inertial navigation.^[63] Missions are coordinated by an automated planning system that can automatically perform all aspects of an attack mission, including weapons release.^[64] Targets are acquired by a thermal imaging infrared system, paired with a laser rangefinder/laser designator that finds the range and designates targets for laser-guided bombs. The F-117's split internal bay can carry 5,000 pounds (2,300kg) of ordnance. Typical weapons are a pair of GBU-10, GBU-12, or GBU-27 laser-guided bombs, two BLU-109 penetration bombs, or after 2006, two Joint Direct Attack Munitions (JDAM) GPS/INS guided stand-off bombs.^[65][66]

Stealth[edit]

The F-117 has a radar cross-section (RCS) of about 0.001m² (0.0108sqft).^[67] Among the penalties for stealth are subsonic speeds to prevent frame heating, heat on the engine inlet and outlet prevent certain thrusting maneuvers, a very low wing aspect ratio, and a high sweep angle (50) are needed to deflect incoming radar waves to the sides.^[13][68][69] With these design considerations and no afterburner, the F-117 is limited to subsonic speeds. Additionally, to maintain its low observability, the F-117 was not equipped with radar; not only would an active radar be detectable through its emissions, but an inactive radar antenna would also act as a reflector of radar energy.^[70] Whether it carries any radar detection equipment remained classified as of 2008.^[13]

Its faceted shape (made from two-dimensional flat surfaces) resulted from the limitations of the 1970s-era computer technology used to calculate its RCS. Later supercomputers made it possible for subsequent aircraft like the B-2 bomber to use curved surfaces while maintaining stealth, through the use of far more computational resources to perform the additional calculations.^[71] The radar-absorbent flat sheets covering the F-117 weighed almost one ton, and were held in place by glue, with the gaps between the sheets filled with a kind of putty material called "butter".^[13][72]

An exhaust plume contributes a significant infrared signature. The F-117 reduces IR signature with a non-circular tail pipe (a slit shape) to minimize the exhaust cross-section and maximize the mixing of hot exhaust with cool ambient air.^[73] The F-117 lacks afterburners, because the hot exhaust would increase the infrared signature, and breaking the sound barrier would produce an obvious sonic boom, as well as surface heating of the aircraft skin which also increases the infrared footprint. As a result, its performance in air combat maneuvering required in a dogfight would never match that of a dedicated fighter aircraft; this was unimportant in the case of the F-117 since it was a dedicated attack aircraft.^[45]

Passive (multistatic) radar, bistatic radar and especially multistatic radar systems detect some stealth aircraft better than conventional monostatic radars, since first-generation stealth technology (such as the F-117) reflects energy away from the transmitter's line of sight, effectively increasing the radar cross section (RCS) in other directions, which the passive radars monitor.^[74]

Operational history[edit]

Early activities[edit]

During the program's early years, from 1984 to mid-1992, the F-117 fleet was based at Tonopah Test Range Airport, Nevada, where it served under the 4450th Tactical Group; Air Combat Command's only F-117A unit.^[75] The unit was headquartered at Nellis Air Force Base. A-7 Corsair II aircraft were used for training. Most personnel and their families lived in Las Vegas. This required commercial air and trucking to transport personnel between Las Vegas and Tonopah each week.^[76] The 4450th was absorbed by the 37th Tactical Fighter Wing in 1989. In 1992, the entire fleet was transferred to Holloman Air Force Base, New Mexico, under the command of the 49th Fighter Wing. ^[75]

The F-117 reached initial operating capability status in 1983.^[2][75] The Nighthawk's pilots called themselves "Bandits". Each of the 558 Air Force pilots who have flown the F-117 has a Bandit number, such as "Bandit 52", that indicates the sequential order of their first flight in the F-117.^[77] Pilots told friends and families that they flew the Northrop F-5 in aggressor squadrons against Tactical Air Command.^[37]

The F-117 has been used several times in war. Its first mission was during the United States invasion of Panama in 1989.^[78][79] During that invasion, at least two F-117s dropped bombs on Rio Hato airfield.^[80][81]

The aircraft was operated in secret from Tonopah for almost a decade, after the Gulf War, all aircraft moved to Holloman in 1992however, its integration with the USAF's non-stealth "iron jets" occurred slowly. As one senior F-117 pilot later said: Because of ongoing secrecy others continued to see the aircraft as "none of their business, a stand-alone system".^[13] The F-117 and the men and women of the 49th Fighter Wing were deployed to Southwest Asia on multiple occasions. On their first deployment, with the aid of aerial refueling, pilots flew non-stop from Holloman to Kuwait, a flight of approximately 18.5 hours.^[82]

Yugoslavia[edit]

One F-117 (AF ser. no. 82-0806) was lost to enemy action. It was downed during an Operation Allied Force mission against the Army of Yugoslavia on 27 March 1999.^[83] The aircraft was acquired by a fire control radar at a distance of 8.1mi (13km) and an altitude of 26,000ft (8km). SA-3s were then launched by a Yugoslav version of the Soviet Isayev S-125 "Neva" (NATO name SA-3 "Goa") anti-aircraft missile system.^[83][84][85] The launcher was run by the 3rd Battalion of the 250th Air Defence Missile Brigade under the command of Colonel Zoltn Dani.^[86]

After the explosion, the aircraft became uncontrollable, forcing the pilot to eject.^[83] The pilot was recovered six hours later by a United States Air Force Pararescue team.^[83][87] The stealth technology from the downed F-117 has reportedly been studied by Russia,^[88] and possibly China as well.^[89] The U.S. did not attempt to destroy the wreckage; senior Pentagon officials claimed that its technology was already dated and no longer important to protect.^[37]

American sources state that a second F-117 was targeted and damaged during the campaign, allegedly on 30 April 1999.^[90][91] The aircraft returned to Spangdahlem Air Base,^[91] but it supposedly never flew again.^[92][93] The USAF continued using the F-117 during Operation Allied Force.^[94]

Iraq and Afghanistan[edit]

During the Gulf War in 1991, the F-117 flew approximately 1,300 sorties and scored direct hits on what the U.S. called 1,600 high-value targets in Iraq^[2] over 6,905 flight hours.^[95] Leaflet drops on Iraqi forces displayed the F-117 destroying ground targets and warned "Escape now and save yourselves".^[39] Only 229 Coalition tactical aircraft could drop and designate laser-guided bombs of which 36 F-117s represented 15.7%, and only the USAF had the I-2000 bombs intended for hardened targets. So the F-117 represented 32% of all coalition aircraft that could deliver such bombs.^[96]:7374 Notably, F-117s were involved in the Amiriyah shelter bombing, killing at least 408 civilians.^[97]

Much media attention was given to the bombing of telecommunications, water, and transportation infrastructure in Baghdad. Stealth bombers were used due to the perimeter of Baghdad being heavily defended with anti-aircraft weapons. Part of the American strategy in targeting the city's infrastructure was to make it unlivable for the populace. The bombings quickly became part of a propaganda battle with media highlighting the killing of civilians and American claims that stealth bombing was highly effective at destroying military targets.^[98] Post war records show that the F-117 had 18 times more targets per aircraft than their non-stealthy peers.^[99]

Outside of Baghdad, the F-117 bombing was primarily used to destroy airfields and it was used in conjunction with other air munitions. Overall, 42 F-117s dropped 2077 bombs in Desert Storm. This accounts for about a third of USAF guided bombing.^[98]

Early claims of the F-117's effectiveness were later found to be overstated.^[100] Initial reports of F-117s hitting 80% of their targets were later scaled back to "4160%".^[96]:132 On the first night, they failed to hit 40% of their assigned air-defense targets, including the Air Defense Operations Center in Baghdad, and 8 such targets remained functional out of 10 that could be assessed.^[96]:136137 In their Desert Storm white paper, the USAF stated that "the F-117 was the only airplane that the planners dared risk over downtown Baghdad" and that this area was particularly well defended. (Dozens of F-16s were routinely tasked to attack Baghdad in the first few days of the war.)^[96]:137138 In fact, most of the air defenses were on the outskirts of the city and many other aircraft hit targets in the downtown area, with minimal casualties when they attacked at night like the F-117;^[96] they avoided the optically aimed anti-aircraft cannon and infrared SAMs which were the biggest threat to Coalition aircraft.^[96]:105

The F-117 was used during Operation Enduring Freedom in 2001.^[101][102] The Taliban lacked a modern Air Force. After the initial bombing campaign in October, targets justifying F-117 usage were limited as was the use of the F-117.^[103]

The first bombs dropped in the 2003 Operation Iraqi Freedom were from two F-117 on the Dora Farms in attempt to assassinate Saddam Hussein. The F-117 was chosen to deliver a bunker buster payload because nearby Baghdad was heavily fortified with anti-aircraft weapons, and US intelligence indicated Saddam Hussein's bunker was too reinforced for missiles. The EGBU-27 Advanced Paveway III bunker buster is an unusual payload for the F-117. Post-facto intelligence showed that Saddam Hussein had been at Dora Farms, but left several hours prior to the bombing. ^[104][105] During this time the Air Force estimated the operational cost as $35,000 per JDAM style bomb delivered by the F-117.^[106]

Program closeout[edit]

The loss in Serbia caused the USAF to create a subsection of their existing weapons school to improve tactics. More training was done with other units, and the F-117 began to participate in Red Flag exercises. Though advanced for its time, the F-117's stealthy faceted airframe required a large amount of maintenance and was eventually superseded by streamlined shapes produced with computer-aided design. Other weapon systems began to take on the F-117's roles, such as the F-22 Raptor gaining the ability to drop guided bombs.^[3] By 2005, the aircraft was used only for certain missions, such as if a pilot needed to verify that the correct target had been hit, or when minimal collateral damage was vital.^[13][9]

The USAF had once planned to retire the F-117 in 2011, but Program Budget Decision 720 (PBD 720), dated 28 December 2005, proposed retiring it by October 2008 to free up an estimated $1.07billion^[107] to buy more F-22s.^[77] PBD 720 called for 10 F-117s to be retired in FY2007 and the remaining 42 in FY2008, stating that other USAF planes and missiles could stealthily deliver precision ordnance, including the B-2 Spirit, F-22 and JASSM.^[108] The planned introduction of the multi-role F-35 Lightning II also contributed to the retirement decision.^[109]

In late 2006, the USAF closed the F-117 formal training unit (FTU),^[110] and announced the retirement of the F-117.^[111] The first six aircraft to be retired took their last flight on 12 March 2007 after a ceremony at Holloman AFB to commemorate the aircraft's career. Brigadier General David L. Goldfein, commander of the 49th Fighter Wing, said at the ceremony, "With the launch of these great aircraft today, the circle comes to a closetheir service to our nation's defense fulfilled, their mission accomplished and a job well done. We send them today to their final resting placea home they are intimately familiar withtheir first, and only, home outside of Holloman."^[112]

Unlike most other USAF aircraft that are retired to Davis-Monthan AFB for scrapping, or dispersal to museums, most of the F-117s were placed in "Type 1000" storage^[113] in their original hangars at the Tonopah Test Range Airport.^[83] At Tonopah, their wings were removed and the aircraft are stored in their original climate-controlled hangars.^[112] The decommissioning occurred in eight phases, with the operational aircraft retired to Tonopah in seven waves from 13 March 2007 until the last wave's arrival on 22 April 2008.^[114][83] Four aircraft were kept flying beyond April by the 410th Flight Test Squadron at Palmdale for flight test. By August, two were remaining. The last F-117 (AF Serial No. 86-0831) left Palmdale to fly to Tonopah on 11 August 2008.^[83][115] With the last aircraft retired, the 410th was inactivated in a ceremony on 1 August 2008.^[116]

Five aircraft were placed in museums, including the first four YF-117As and some remains of the F-117 shot down over Serbia. Through 2009, one F-117 had been scrapped; AF Serial No. 79-0784 was scrapped at the Palmdale test facility on 26 April 2008. It was the last F-117 at Palmdale and was scrapped to test an effective method for destroying F-117 airframes.^[83]

Congress had ordered that all F-117s mothballed from 30 September 2006 onwards were to be maintained "in a condition that would allow recall of that aircraft to future service" as part of the 2007 National Defense Authorization Act. As of 2022, USAF plans to demilitarize three F-117s each year until 2034 when they should all be demilitarized.^[117][118]

Post-retirement service[edit]

The service is using the aircraft in aggressor squadron and cruise missile training, and research and development. USAF has also slowed the retirement of its current inventory of about 45 F-117s to two to three units a year. This plan should extend the lifetime of the F-117 program to 2034.^[118][117]In March 2019, it was reported that four F-117s had been secretly deployed to the Middle East in 2016 and that one had to make an emergency landing at Ali Al Salem (OKAS), Kuwait sometime late that year.^[119]

On 13 September 2021, a pair of F-117s landed at Fresno Yosemite International Airport in California. They were scheduled to train with the California Air National Guard F-15C/D Eagles of the 144th Fighter Wing over the next few days.^[120] One aircraft had red letters on its tail, and the other had white letters. One of the two was observed to not be fitted with radar reflectors.^[121] That year USAF published photographs on DVIDS, the first acknowledgement by the service that the aircraft continued to fly after its official retirement.^[118]

In January 2022, two F-117s were observed in flight in the Saline Military Operating Area. One had portions of its exterior covered in a "mirror-like coating" believed to be an experimental treatment to reduce the aircraft's infrared signature.^[122]

In May 2023, an F-117 participated in exercise Savannah Sentry at the Air Dominance Center in Savannah, Georgia. It was a joint exercise with both active USAF and Air National Guard units. In a video documenting the exercise, an off-screen crew member stated that there are approximately 48 flyable F-117s in USAF inventory. They stated that the F-117 is sometimes used in aggressor-type training roles and was brought to Savannah Sentry to participate in an "unclassified capacity."^[123] On 1 February 2024, two F-117s were seen at testing range R-2508 in the Mojave Desert.^[124]

Variants[edit]

F-117N "Seahawk"[edit]

The United States Navy tested the F-117 in 1984 but determined it was unsuitable for carrier use.^[39] In the early 1990s, Lockheed proposed an upgraded carrier-capable F-117 variant dubbed the "Seahawk" to the Navy as an alternative to the canceled A/F-X program. The unsolicited proposal was received poorly by the Department of Defense, which lacked interest in the single mission capabilities on offer, particularly as it would take money away from the Joint Advanced Strike Technology program, which evolved into the Joint Strike Fighter. The F-117N would have differed from the land-based F-117 in several ways, such as the use of "elevators, a bubble canopy, a less sharply swept wing and reconfigured tail".^[125][126] It would also be re-engined with General Electric F414 turbofans in place of the General Electric F404s. The aircraft would be optionally fitted with hardpoints, allowing for an additional 8,000lb (3,600kg) of payload, and a new ground-attack radar with air-to-air capability. In that role, the F-117N could carry AIM-120 AMRAAM air-to-air missiles.^[125][127]

After being rebuffed by the Navy, Lockheed submitted an updated proposal that included afterburning capability and a larger emphasis on the F-117N as a multi-mission aircraft, rather than just an attack aircraft.^[127] To boost interest, Lockheed also proposed an F-117B land-based variant that shared most of the F-117N capabilities. This variant was proposed to the USAF and RAF.^[128] Two RAF pilots formally evaluated the aircraft in 1986 as a reward for British help with the American bombing of Libya that year. RAF exchange officers began flying the F-117 in 1987,^[39] but the British declined an offer during the Reagan administration to purchase the aircraft.^[129] This renewed F-117N proposal was also known as the A/F-117X.^[130] Neither the F-117N nor the F-117B were ordered.

F-117A

Nicknames[edit]

The aircraft's official name is "Night Hawk",^[149] with the alternative form "Nighthawk" also used.

As it prioritized stealth over aerodynamics, it earned the nickname "Wobblin' Goblin" due to its alleged instability at low speeds. However, F-117 pilots have stated the nickname is undeserved.^[150] "Wobblin' (or Wobbly) Goblin" is likely a holdover from the early Have Blue / Senior Trend (FSD) days of the project when instability was a problem. In the USAF, "Goblin" (without wobbly) persists as a nickname because of the aircraft's appearance. During Operation Desert Storm, Saudis dubbed the aircraft "Shaba", which is Arabic for "Ghost".^[151][152] Some pilots also called the airplane the "Stinkbug".^[153]

During the NATO bombing of Yugoslavia in 1999 it picked up the nickname "Invisible" (Serbian Cyrillic "", Latin "Nevidljivi"). The name became ironic after it was shot down over Serbian airspace near Buanovci, leading to the phrase "we didn't know it was invisible".^[154]
